The object of this invention is to provide improved means for causingthe admixture of hydrocarbon fluid and air after they leave a carbu eterand as they enter or pass through the intake pipe leading from thecarburetor to the manifold or engine cylinders. In devices of the kindheretofore, the

difficulty has been that the intake pipe would become loaded. By this ismeans that there would be a heavy deposit of the hydrocarbon, inglobules, on the inner wall of the intake pipe and the air would not mixeffectively, but would point away from and pass said globules.Heretofore, the hydrocarbon instead of mixing with the air and goinginto the cylinder of the engine, has, to too great an extent, beendeposited on or has adhered to the wall of the intake pipe andaccumulated there until it is in a mixture of the desired proportion ofhydrocarbon, but has interfered materially with the operation of thedevice. 1

The chief feature of my invention consists in arranging a screen in theintake pipe at an inclination and to a greater or less degree inclinedin or parallel with the direction of movement of the air after it passesthe throttle valve so that the hydrocarbon particles could deposit onlyon the screen and the deposit, by reason of the inclination of thescreen, would be substantially uniform and the air, would, therefore,come in a direct and substantially uniform contact with the screen andforce itself through the screen and thus take up constantly theparticles of hydrocarbon, as it passes through the screen, so as toprevent any excessive deposit of hydrocarbon and to cause thehydrocarbon to be taken up with the air and carried into the cylinders.

The nature of the invention will be understood from the accompanyingdrawings and the following description and claims.

In the drawings, Figure 1 is a side elevation of a carburetor with theupper part thereof and the lower part of the intake pipe 1n centralvertical section, parts being broken away. Fig. 2is a perspectivev Viewof the screen and means for supporting the same. through the outlet pipeof the carbureter and intake pipe, parts being broken away. F 1g. 4 isthe same with the screen included and showing the passage of air andfuel therethrough.

A carbureter 10 of any type may be em ployed, having an outlet pipe 11secured to an engine intake pipe 12 by screws 13. A throttle valve 14may be placed in either the outlet pipe 11 or intake pipe 12, asdesired.

My invention consists in placing a screen and the means for supportingit in the intake pipe beyond or above the throttle valve, whether thelatter be in the intake pipe or the outlet pipe from the carbureter. Themeans for supporting the screen 15 consists of a tbue 16 with an annularcollar 17 on one end adapted to lie between the 'fianges on the ends ofthe pipes 11 and 12 and have the screw 13 to pass through so to clampthe collar and pipe 17 securely in place in the pipe 12. The other endof the pipe 16 is cut at an angle of about forty-five degrees and thescreen 15 secured thereon so that it will be inclined at said angle.Preferably the intake pipe should be bored out to make an annular recess18 of about the same thickness as the pipe 16 for the purpose ofreceiving and securing said pipe 16. That leaves the passageway throughthe pipes 11, 16 and 12 smooth and of the same diameter, which isimportant. Furthermore, the tube 16 is so arranged in the intake pipewith reference to the throttle valve, that the lower end of the screen15 will be located on the same side of the passageway at which the majorportion of the mixture passes the throttle valve. In other words, thethrottle valve opens toward the lower end of the screen or the endnearest the throttle valve and deflects nearly all of the mixture tothat side of the passageway so that it first strikes the lower part ofthe screen and travels up the underside of'the screen to a greater orlesser extent so that the passage of air or mixture through the parts ofthe screen will be substantially equal or uniform, as indicated in Fig.4. This will cause small particles of the fuel to lodge on the screen,but

Fig. 3 is a central vertical section.

the air will constantly sweep through the screen adjacent said particlesand take them almost as soon as they are deposited. This will cause theuniform and satisfactory admixture of the elements of the mixture andcarry the fuel into the cylinder and prevent the fuel accumulating inthe intake pipe. Very little fuel can accumulate in the tube 16 belowthe lower part of the-screen because it'will be taken up by the greatsweep of air over that surface. Not very much accumulates on the otherside of the pipe 16, because not very much mixture passes the valve atthat side. Probably more than four-fifths of the mixture on the averageis deflected past the other side of the valve.

Fig. 3 illustrates the means heretofore employed and the manner in whichthe fuel accumulates in the intake pipe and loads it. The object of thisinvention is to avoid that result, that loading.

I claim as my invention:

1. A gaseous fluid mixer including a conduit, a tilting throttle valvetherein, and a screen located in said conduit immediately beyond thevalve and in an oblique position.

2. A gaseous fluid mixer including a'conduit, a tilting throttle valvetherein, and a screen located in said conduit immediately beyond thevalve and in an oblique position,

the valve and screen being relatively arranged so that the valvedeflects the gaseous fluid toward the nearer part of the screen.

3. A gaseous fluid mixer including a conduit having a straight portion,a throttle valve therein, a screen holding pipe secured in said conduitin the straight portion thereof beyond the throttle valve with its innerend cut off obliquely, and a screen secured on said inclined end of saidinserted pipe.

at. A gaseous fluid mixer including a pipe having a radial flange, asecond and continuing pipe having a straight portion bored out toprovide a recess in the inner Wall thereof,

a throttle valve in one of said pipes, another 1 pipe within the recessin the straight portion of said second pipe and having a radial flangelocated between the two flanges of said pipes, screws extending throughall of said flanges for clamping them together, the inner end of saidinserted pipe being cut oif obliquely, and a screen secured to the innerend of said inserted pipe.

In Witness whereof, I have hereunto affixed my signature in the presenceof the witnesses herein named.
